BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire vulcanizing equipment used in parallel with a tire vulcanizer.

[0002]

2. Description of the Related Art In a conventional full-automatic tire vulcanizing press, an unvulcanized tire is compared with a vulcanization reaction time when a heating and pressurizing medium is introduced into the tire with the tire mold assembly closed. The work time for loading, shaping, and removing the vulcanized tire is very short, and then the tire mold opening and closing device and the tire loading and unloading device that open and close the tire mold assembly for tire loading and unloading etc. The rate is bad.

In view of this point, the applicant of the present invention has

Place it on the lower rim. When the vulcanized tire is left stationary, the grip is closed (the upper rim is lowered), the upper and lower rims are locked by the action of the lock driving means, and then the tire is filled with compressed gas. (3) When the filling of the compressed gas is completed, the cock valve is closed, and then the gripping unit is transferred to a predetermined position in the cooling station by the mold carrier to continue the cooling.
(4) When it is necessary to change the rim size, change the rim spacing, or clean the rims contaminated with oil smoke or tar with the gripping unit that has taken out the cooled tire, replace the tire in (1) above. After taking out the work, lower the upper rim without installing the tire to make a gripping unit that does not grip the tire, release the connection with the gripping unit opening / closing station, and store it via the temporary stand. When returning to the station, a new gripping unit prepared in advance is installed in the opening / closing station via the temporary placing table, or is passed and moved to an empty place of the cooling station to stand by.
